Samudra u & ur country shud not worry about it. ur technology have been begged from Israel & some from russia. But alhamdulilah our defenders are The Momins.& Allah always help Momins. As u & israel have tried many attempts on us but SO SAD.........!

 

[Engr786]

There is not even a single case in which Pakistani missile failed to achieve the goal. But I can prove several indian missiles that could not even cover the specified ranges.

It's all because we work up to the top. As we r not a low level people...!

Successful Commissioning of the upgraded COSPAS-SARSAT Mission Control Center in Pakistan
SUPARCO has successfully completed Commissioning Test of Pakistan Mission Control Center at SUPARCO HQs Karachi under COSPAS-SARSAT International Program for support of Search and Rescue using satellite aided tracking technology.
COSPAS-SARSAT is an international satellite-based search and rescue system, established by Canada, France, the United States and the Soviet Union in 1979.
The Commissioning Test was carried out from 10 Nov 2009 at 0500 - 1300 UTC to 12 Nov 2009.
Successful completion of Commissioning test recognized Pakistan as a member of the International COSPAS-SARSAT Program.
COSPAS-SARSAT program accrues the following benefits to Pakistan for efficient search and rescue operations.
• An early indication of a possible air crash, a marine accident or beacon-equipped person in distress by receiving a radio distress signal.
• Detection and location of distress beacons thus avoiding grid searches by a search and/or rescue aircraft which are time-consuming and highly expensive.
• Safety of the personnel involved in search and rescue from unnecessary risks by accurate location of the distress signals.
• Prompt detection of distress signals within an hour or so, due to the network of low earth orbiting operational satellite.

Pakistan has a leased satellite, PAKSAT-1, in the 38 degree East longitude geostationary orbit. The government of Pakistan has granted approval for the replacement of PAKSAT-1 by a new communication satellite PAKSAT 1R by 2011. SUPARCO has also developed a prototype of a communication satellite named Prototype PAKSAT-1R and is now developing an Engineering Qualification Model (EQM).

 

[Ababeel]

By the end of 2011, Pakistan plans to replace PAKSAT-1 with a new communication satellite PAKSAT-1R which will be manufactured exclusively for Pakistan. The satellite will support all conventional and modern Fixed Satellite Service (FSS) applications. The satellite will have a total of up to 30 transponders: 18 in Ku-band and 12 in C-band. To ensure high degree of reliability / availability of the system, two (02) fully redundant Satellite Ground Control Stations (SGCS) would be established in Karachi and Lahore, one to act as the Main and the other as Backup respectively.

Prototype PAKSAT 1R:
The project was aimed to enhance the know-how of young scientists and engineers about communication satellite engineering. The philosophy was to design a satellite such as it would fly, however, while implementing the design, use commercial components to keep the cost low since the satellite will only be a functional lab model.

Prototype Paksat-1R is a communication satellite, which has three C-band Transponders as the communication payload. All the subsystems have been designed and developed indigenously. Integration and testing have also been performed. The project was completed in three years time.

The satellite bus comprised the following subsystems:

.

(i) Computer (based on Intel 80188EB microprocessor)

.

(ii) Power subsystem with the following main modules:
a.Power Distribution
b.Power Control
c.Battery Charging and Discharging
d.BAPTA

(iii)
Telemetry subsystem
a.Microcontroller based
b.FPGA based

(iv) Telecommand subsystem
a.Microcontroller based
b.FPGA based

(v) Attitude and Orbit Determination and Control subsystem

(vi) S-band RF communication subsystem (for telemetry and telecommand)

(vii) Thermal Control subsystem

(viii) Satellite Structure

(ix) Mechanisms for:
a.Antenna Deployment
b.Solar Array Deployment

Pardon my nitpicking ... but could not stop myself from taking a dig at the title of this thread which says:

"Pakistan Space and Satellite Developments"

Pakistan can develop satellites but how can Pakistan develop Space !?

 

[Ababeel]

It should be space technology

Engineering Qualified Model (EQM) of a Small Communication Satellite:
As a first step towards the ultimate goal of achieving self-reliance in the field of design and development of communication satellites, SUPARCO has lately been involved in the design and development of prototype of a communication satellite named Prototype Paksat-1R. The project was completed in 2005. As a next step forward in achieving self reliance in development of a flight worthy satellite, SUPARCO now intends to develop the Engineering Qualification Model (EQM) of a small communication satellite. Engineering Qualified Models (EQMs) are more efficient and reliable / robust than prototypes but are not qualified to fly, for which Flight Models (FMs), that can withstand the rigours of launch and space environment, are required. To achieve this goal, EQM for 05 subsystems were designed and developed to be followed by the remaining ones to complete the satellite. The EQMs of the following subsystems were designed, developed and tested:

On-Board Computer (OBC)
Telemetry Subsystem
Telecommand Subsystem
C-band Transponder
S-band Communication subsystem

Development of Satellite Facilities



.

To achieve the objective of indigenous satellite development, SUPARCO has embarked upon a plan to develop the necessary infrastructure for Satellite Assembly Integration and Test (AIT). In this regard the following facilities have been/are being established:

.

Satellite Assembly Integration & Test (SAINT)

.

The Assembly integration and testing of satellites is carried out in specialized cleanroom facilities. A ‘Satellite Assembly Integration and Test (SAINT) facility’ was commissioned at Satellite Research and Development Center, Lahore in 2007. The facility caters for the AIT requirements of small to medium sized satellites. It consists of a cleanroom of class 100,000 High Bay for satellite integration and functional testing and cleanroom of class 10,000 for assembly of satellite sub-systems. The Prototype Paksat-1R satellite was integrated and functionally tested in this facility.

Environmental Validation Testing (EVT) Facility

.

For the qualification of any satellite before it can be launched, its performance needs to be tested and verified not only functionally but also from the environmental point of view as the satellite will have to undergo harsh environmental conditions in space both during the launch and operations in space. To meet this requirement an EVT facility was planned at SRDC-L which is currently under development. It would have facilities for vibration, thermal vacuum, shock, mass properties and pressure testing of small to medium sized satellites.


Compact Antenna Test Range (CATR) Facility

.

The CATR facility is currently under development at SRDC-L. The objective of the facility is to test and validate key RF performance parameters (e.g. EIRP, G/T, coverage pattern/ foot prints, frequency and beam steering, etc) of satellites of various kinds and other complex radiating systems, with capability to handle frequencies from 1 to 40 GHz and antenna sizes of up to 3m in diameter.


SAINT Support Workshop (SSW) Facility

.

The SSW facility has a workshop to facilitate in-house manufacturing/ fabrication of mechanical and microwave components warranting high precision and quality, which are required for supporting R&D activities relating to the design and development of prototype and engineering model satellites. The workshop would have various CNC and conventional machines. The facility is currently under construction.


Clean Room

.

A class 10,000 clean room facility has been established for assembly, integration and testing (AIT) of imaging payloads for LEO Satellites. Inside this facility, a class 1,000 soft wall capsule for the assembly and testing of optical components has also been established. AIT of Prototype PRSS was performed in this facility.

Environmental Chamber

.

An Environmental Protection Chamber was constructed to test various components, devices, sensors, modules and antennas of remote sensing satellites in open environment. The Chamber is made of composite material (fiber glass), aluminum and stainless steel to make this chamber durable in open to sky environment. The special function of this protection chamber is removable top roof controlled by a hydraulic system to make experiments on satellite in an open to sky environment. At the center of the chamber, elevation over azimuth position is available that can rotate and elevate satellite under experiment.

When will Suparco launch its SLV?

I find it hard to believe that a nation that is capable of making missiles that travel a few thousand kilometers - exit the atmosphere and re-enter it cannot make a simple SLV.Something must be wrong.

I read about Pakistan's space program a long time ago. Can't remember it now. But as far as I know, Pakistani space programs was launched in early 60's, probably in 64. In the very next year, Pakistan, as far as I remember, announced its plans to launch SLV, but what happened to it after one year of affective start of our space program in now a big conspiracy.

Not only the space program, but many other critical projocts are either abandoned or delayed due to foreign pressure. Long list include construction of Kalabagh Dam, reconstruction of GT Road and double lanes of Railway.

samudra, one thing I can tell you for sure. Pakistan not only posses all the required capabilities but technology too. Sending a rocket to the moon or a missle to other country does not have too much difference. May be, it is also due to non availability of sincere and good quality leadership. Overall, leaders like nawaz are not needed, who speak loudly before the war and then go pussy during it.
